Abstract

Procedimiento y aparato para el tratamiento de agua residual, incluyendo el procedimiento una etapa en la cual se separa un gas de un líquido, caracterizándose el procedimiento porque comprende reducir la presión sobre la superficie del agua residual, durante la etapa de separación de gas, a un valor inferior a la presión atmosférica, en un grado suficiente para causar la liberación de una proporción de cualquier gas disuelto o burbuja presente en el agua residual.
